The 2015 EU Energy Union Package proposes integrating renewables into the market, just as the UK has moved away from Premium Feed-in Tariffs (FiTs) for renewable electricity supply (RES-E) to something closer to the standard FiT, which, when auctioned, demonstrated a 3% real fall in the weighted average cost of capital (WACC). The UK, which has experimented with nearly all forms of RES-E support, offers the evidence base for designing the Energy Union's RES-E support. Innovation needs a further redesign to deliver adequate funding, best done through country contributions to an EU-wide innovation competition. (C) 2016 Elsevier Ltd. All rights reserved.
